What will humans evolve into next?
We will likely live longer and become taller, as well as more lightly built. We'll probably be less aggressive and more agreeable, but have smaller brains. A bit like a golden retriever, we'll be friendly and jolly, but maybe not that interesting. At least, that's one possible future.
We are currently in the midst of the next great evolutionary transition: the transition to Conscious Evolution.
In the next 1,000 years, the amount of languages spoken on the planet are set to seriously diminish, and all that extra heat and UV radiation could see darker skin become an evolutionary advantage. And we're all set to get a whole lot taller and thinner, if we want to survive, that is.
The last “sympatric” humans we know of were Neanderthals, who became extinct only about 30,000 years ago. Since stable separation of parts of the species is the key factor for the formation of new species, we can say that a new split of our species is impossible under current circ*mstances.
What is clear however, is that all organisms are dynamic and will continue to adapt to their unique environments to continue being successful. In short, we are still evolving.
Over time, genetic change can alter a species' overall way of life, such as what it eats, how it grows, and where it can live. Human evolution took place as new genetic variations in early ancestor populations favored new abilities to adapt to environmental change and so altered the human way of life.
When non-avian dinosaurs went extinct 66 million years ago, mammals rose to fill many of their vacant niches. If humans were to disappear, it's possible that birds, the only surviving dinosaurs, could fill our roles as the smartest and handiest land animals.

Humans are still evolving: 3 examples of recent adaptations
- We are cooling down. ...
- Our genes are constantly changing. ...
- Our bones are becoming lighter.
The basic rationale behind the conclusion that human evolution has stopped is that once the human lineage had achieved a sufficiently large brain and had developed a sufficiently sophisticated culture (sometime around 40,000–50,000 years ago according to Gould, but more commonly placed at 10,000 years ago with the ...
Humanity has a 95% probability of being extinct in 7,800,000 years, according to J. Richard Gott's formulation of the controversial Doomsday argument, which argues that we have probably already lived through half the duration of human history.
What will humans look like in 100000 years?
100,000 Years From Today
We will also have larger nostrils, to make breathing easier in new environments that may not be on earth. Denser hair helps to prevent heat loss from their even larger heads. Our ability to control human biology means that the man and woman of the future will have perfectly symmetrical faces.
But even if that common ancestor still existed, the fact that evolution is the result of both random mutation and a process of natural selection imposed by environmental conditions, means it's highly unlikely that it would ever retrace its steps in quite the same way.
Within the next 200 years, humans will have become so merged with technology that we'll have evolved into "God-like cyborgs", according to Yuval Noah Harari, an historian and author from the Hebrew University of Jerusalem in Israel.
This took more than 350 million years. There are humans (Bajau Laut- sea nomads) who can hold their breath for longer durations (up to some minutes) underwater. However, it is biologically impossible to evolve (or devolve) to live underwater in a short period.
Modern humans originated in Africa within the past 200,000 years and evolved from their most likely recent common ancestor, hom*o erectus, which means 'upright man' in Latin. hom*o erectus is an extinct species of human that lived between 1.9 million and 135,000 years ago.
The First Humans
One of the earliest known humans is hom*o habilis, or “handy man,” who lived about 2.4 million to 1.4 million years ago in Eastern and Southern Africa.
Humans have certainly had a profound effect on their environment, but our current claim to dominance is based on criteria that we have chosen ourselves. Ants outnumber us, trees outlive us, fungi outweigh us. Bacteria win on all of these counts at once.
The great apes are considered to be the smartest creatures after humans. Among them, orangutans stand out as being especially gifted with brain. They have a strong culture and system of communication, and many have been observed to use their tools in forest.
Chickens do not have the immune strength nor the instinct to survive without us. Cows, if not milked, will continually produce milk, causing them to be in extreme pain. Small dogs cannot survive in the wild, as well as sheep. These animals will all die if we let them go into the wild.
Human traits that emerged recently include the ability to free-dive for long periods of time, adaptations for living in high altitudes where oxygen concentrations are low, resistance to contagious diseases (such as malaria), light skin, blue eyes, lactase persistence (or the ability to digest milk after weaning), lower ...
What was the color of the first humans?
From about 1.2 million years ago to less than 100,000 years ago, archaic humans, including archaic hom*o sapiens, were dark-skinned.
hom*o sapiens evolved from their early hominid predecessors between 200,000 and 300,000 years ago and developed a capacity for language about 50,000 years ago.
Recently, researchers uncovered a genetic clue about why humans have no tails. They identified a so-called jumping gene related to tail growth that may have leaped into a different location in the genome of a primate species millions of years ago. And in doing so, it created a mutation that took our tails away.
In 100 years, oceans will most likely rise, displacing many people, and it will continue to become warm and acidic. Natural disasters like wildfires and hurricanes will continue to be very common and water resources could be scarce. NASA is researching earth to make observations that will benefit everyone.
No matter how advanced technology gets, it might be impossible for our bodies to go on forever. Some researchers believe there's a limit on how long it's physically possible to live: perhaps 125 years.
The upshot: Earth has at least 1.5 billion years left to support life, the researchers report this month in Geophysical Research Letters.
Cryonics holds out the hope that the dead can be revived in the future, following sufficient medical advancements. While, as shown with creatures such as hydra and Planarian worms, it is indeed possible for a creature to be biologically immortal, it is not known if it will be possible for humans in the near-future.
By 2050, about 75% of the world population will be living in cities. Then there will be buildings touching the sky and cities will be settled from the ground up. Roads will be built up to several floors. And to move around, the buildings will be connected to the skywalk.
World population is expected to increase from 7 billion today to over 9 billion in 2050. A growing population is likely to increase pressures on the natural resources that supply energy and food. World GDP is projected to almost quadruple by 2050, despite the recent recession.
Genetic bottleneck in humans
The Youngest Toba eruption has been linked to a genetic bottleneck in human evolution about 70,000 years ago; it is hypothesized that the eruption resulted in a severe reduction in the size of the total human population due to the effects of the eruption on the global climate.
What makes a human human?
human being, a culture-bearing primate classified in the genus hom*o, especially the species H. sapiens. Human beings are anatomically similar and related to the great apes but are distinguished by a more highly developed brain and a resultant capacity for articulate speech and abstract reasoning.
Strength changes
While there is no proof that modern humans have become physically weaker than past generations of humans, inferences from such things as bone robusticity and long bone cortical thickness can be made as a representation of physical strength.
With the exception of Neanderthals, they had smaller skulls than we did. And those skulls were often more of an oblong than a sphere like ours is, with broad noses and large nostrils. Most ancient humans had jaws that were considerably more robust than ours, too, likely a reflection of their hardy diets.
With lower gravity, the muscles of our bodies could change structure. Perhaps we will have longer arms and legs. In a colder, Ice-Age type climate, could we even become even chubbier, with insulating body hair, like our Neanderthal relatives? We don't know, but, certainly, human genetic variation is increasing.
The Egyptians were the first people to record methods for treating water. These records date back more than 1,500 years to 400 A.D. They indicate that the most common ways of cleaning water were by boiling it over a fire, heating it in the sun, or by dipping a heated piece of iron into it.
Ever since researchers sequenced the chimp genome in 2005, they have known that humans share about 99% of our DNA with chimpanzees, making them our closest living relatives.
The data shows modern humans started wearing clothes about 70,000 years before migrating into colder climates and higher latitudes, which began about 100,000 years ago. This date would be virtually impossible to determine using archaeological data because early clothing would not survive in archaeological sites.
Q: If human babies cannot survive on their own, how did the first human baby survive on its own? A: Either they appeared as grown-ups by magic, or they were nursed by their one-mutation-away-from-hom*o-sapiens parents.
Summary: A team of anthropologists that studied chimpanzees trained to use treadmills has gathered new evidence suggesting that our earliest apelike ancestors started walking on two legs because it required less energy than getting around on all fours.

What is the process of evolving called?
Natural selection is the process through which species adapt to their environments. It is the engine that drives evolution.
A new genetic study suggests all modern humans trace our ancestry to a single spot in southern Africa 200,000 years ago.
The First Humans
One of the earliest known humans is hom*o habilis, or “handy man,” who lived about 2.4 million to 1.4 million years ago in Eastern and Southern Africa.
Humans now evolve faster than ever, and it's not because of genes. At the mercy of natural selection since the dawn of life, our ancestors adapted, mated and died, passing on tiny genetic mutations that eventually made humans what we are today. But evolution isn't bound strictly to genes anymore, a new study suggests.
Modern humans originated in Africa within the past 200,000 years and evolved from their most likely recent common ancestor, hom*o erectus, which means 'upright man' in Latin. hom*o erectus is an extinct species of human that lived between 1.9 million and 135,000 years ago.
Adam is the name given in the Bible (Genesis 1-5) to the first human.

Natural disasters like wildfires and hurricanes will continue to be very common and water resources could be scarce. NASA is researching earth to make observations that will benefit everyone.
The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old. The signals consisted of a type of carbon molecule that is produced by living things.
All life on Earth evolved from a single-celled organism that lived roughly 3.5 billion years ago, a new study seems to confirm. The study supports the widely held "universal common ancestor" theory first proposed by Charles Darwin more than 150 years ago.
Many scientists believe that RNA, or something similar to RNA, was the first molecule on Earth to self-replicate and begin the process of evolution that led to more advanced forms of life, including human beings.
